A link 65 is pivoted Iat vone end 'to an arm: 66 extending from"collar,62. V.'.Ifhe vtwo ends of bell; cra-nklever63 are forked and a pin 67 injone of theseends passes through a slot 68 inv the end of Vvlink T6 Ball .i bearing .75 is interposed between bearing'. ,51

Y f f A-collar 76 is pinned to rock shaft 59'immediately'belowj bearingfl. UA rearwardly extending,armi78y onjcollari76 carries a cani roller 79 in position to be engaged by a cam 80. The cam 80 is constructed with slots 81 through which extend bolts 82 connecting thc lam adjustably to a suitable disk carried on shaft 42. A collar S3 is attached to rock shaft 59 by a pin S4, and has a rearwardly extending arm 85. Aspring 8h normally draws the end of arm S towards a lug Si' formed on hub casting 20, and thereby roller T9 is held against cam 80.

A cup nut S8 is screwed on to the lower end of rock shagl't 59. A tool carrier 99 has a` collar 90 loosely mounted on rock shalt 59 and resting upon cup nutlSS. A spring- 91 between collar 76 and collar 90 insures that collar 90 will always remain in position against cup nut 88. j

A vertical lugr 92 rises from tool carrier 89 between the arms of fork 93 on collar 7G. Adjusting nuts 94 pass through the arms of tork 93 to `adjust lug 92 with relation to the rock shaft. An arm 95, carrying at its outer A end suitabletools 96, is pivoted at 97 to y on theend of cam member 89. Lug 98, extending from arm 95, is pressed by spring 99 so as to swing arm a limited distance towards a tumbler restin upon the work support. y

racket 11 has a forwardly extending arm 100 having a bearing 101 for a shaft 102, which carries a circular brush member 103. A pan 104 containing yan abrasive mixture 105 is positioned upon extension 100 in such position that brush member 103 will enter the abrasive material. Cain shaft 4t2 is driven from ,any suitable source, as by` a sprocket chain 106 driving sprocket wheel 107 attached to the cam shaft. A belt pulley 108 shaft 42 drives a belt109, which passes over a pulley 110 on the end of shaft 102 and thereby drives the brush. Spindle operating shaft 52 may be driven from any suitable source, as by aV belt driving` pulley 111 on the end of the shaft. In Fig. 2 there are shown in plan view two similar banding machines mounted side by side and having certain elements in common. `As these two machines are identical in all respects, the corresponding parts are identified by the same reference characters, but itwill bel seen that theparts are in dit` ferent positions of their cycle in the two machines. the partstof the upper machine being in the positions indicated` in Fig. 1, while the position of the spindle, ctc., of the inachine in the lower position is indicated in 'ghe operation ofthe apparatus is substantially as follows lVith the sleeve, and consequentlythe spindle, raised as shown in Fig. l, a tumbler is placed by the operative on the stationary article support 13. The tumbler is readily centered by plate 17 and the lower edge is frictionally engaged by rubber disk 16. The articleretains its position on the support,

so that the operative may release it at once al'ter it has been placed in position. In this position of the apparatus, the tool carrier is held by cam 80 in the position indicated in thc upper part of Fig'. 2, `so that the tool is out olf Contact with the tunlbler. j j

As shaft 42 revolves, cam `lll-l allows sleeve 20 to lower until. plate 38 rests upon the upper end ol the tumbler. Cain 80 is so ad justed that it allows rock shaft 59 to be rocked by spring' S6 and at siibstantially the same time that the spindle is` lowered, but the rocking oit' the shaft is not completeduntil al'ter plate SSrests on the tumbler. Look` ing at the apparatus in the upper part oit Fig. 2, it `will be readily sccn thatfas link 65 moves to the right, spring 72 will"force clutch member 71 towards pulley 53` and maintain pins 6l" at the outer `end off slot GS until the clutch member contacts "the pulley. The parts are so timed that this y will occur immediately alter the oit.' the tumbler by plate 38. j Y i 'tter clutch member `7l contacts pulley 53 and rotation ot the spindle andwvork is thereby begun, roch shaft 59 continues to rock. During;` this continued movcincutof rock shaft 59, link (i5 moves to the `right without affecting bell crank lever 63 because of the lost motion `allowed by `slot 68. `This roel-:ing movement of shaft 59 continues until tool 90 carried into Contact with the tumbler, and the pressure ol the tool against the tumbler is regulated by spring`99, which may be made adjustable, it desired, by means not shown. Brush 103 lightly contacts the front side oit' thetnmble r an abrasive mixture and, as the tun'ibler smeared with this abrasive mixture ro-` tated in Contact with the tool, suitable bands 112are formed thereon'.` The toolsare constructed and arranged in accordance with the design desired. j y 'j f After a suitable interval, cam`80`again rocks shaft 59, first carrying the tool out "ol contact with the tumbler and then, when the lost motion provided by slot 08 is taken up, withdrawing clutch njicinberi'l so that the spindle is stopped. About the same time :am tlf-3 raises the spindle so that thetumbler may engagen'lent be removed and another `article lputin its place. `The time duri; r which the tool should contact the article is dependent upon seve'al variable factors, amongst which the pressure ot the tool. This pressure may bc regulated by adjustingr springl 99, and to some extentby adjustment "ot nuls 941i; Nuts 94 may be used to vary the duration of the contact of the tool, as well as the degree of pressure, and to adjust the position olf `the holder as the tool wearsy auuiy. Cam 80 may be adjusted to properly timcthe lative movements, preterallily so that rotation starts after the article is contacted by the spindle and ceases bet'ore the spindle is raised, and

an d smears it with begins f to rotate 'an tended by one operator.

vto hold the article sof'that theitool'en i" es'theartiClVffilt it is still rotating.` v a' Y 'As willpb'e readily E' seen, I have'fdevised apparatusV which allows of" a number of fbanding devices beingplaced .closely adjacent to each otherk where""they*may be readily at- As .the tumbler may be removed at any time after the spindle is raised and as the tumbler willmaintain its position when dropped into place upon the `article carrier, the operative is not compelled to remove the article at the instant when the spindle is raised and does not have in position until the spindle is lowered. lAllthat is required is that the removal and replacement shall take place some time while the vspindle is raised.

This allows an appreciable latitudevin the movements ofthe operative and makes feasible the operation of a plurality of devices by one person', ther by saving considerable handlaboit `As will be seen bythe arrows on Fig-s.V l and 3, I prefer'to drive the abrasive-apply- 1 ing'brush so that its side in contact with the article moves downward. brush againstthe article is light, so that it lplaced thereon,

tomatic means The contact of the is not likely to disturb the article, whatever its direction of rotation, but the arrangement shown prevents any possibility of such result.

I have mentionedrubber as anespecially suitable material for the parts engagingrthe f article, but other materials might be used. The Aparticular suitability ofrubber lies in its yielding nature and` its frictional surface.

The work support is so lconstructed thatit automatically centers by gravity an karticle and holds the article in substantially centered position when merely dropped thereon. This enables the operative to position the article with the minimum of time and care. At the same time, lboth spindle and tool are so constructed 'that slight irregularity in the structure of the article or slight inaccuracy in its centering is not fatal to the success of the banding operation. n

While I have disclosed in considerable detail one embodiment of my invention, it will be readily apparent tions can be made-therein within the scope of the appended claims which define my invention.
